What four factors were used to make this product game board 9. 15 18. 21 ? 30 35. 36 42 49

The required four factors were used to make this product game board is 2, 3, 5 and 7.

Step-by-step explanation:

Consider the provided numbers.

Now find the prime factorization of each number as shown.

Now, consider above prime factorization there are 4 factors used to produce the numbers.

The four factors are 2, 3, 5 and 7.

Hence, the required four factors were used to make this product game board is 2, 3, 5 and 7.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
